本文介绍1992年在昆明市官渡区福海乡所做施肥时间实验与稻曲病发生的关系。施肥期分栽秧当天。栽后10天、栽后25天、栽后40天及空白对照。结果表明,处理间孕穗前期叶色级别与病害相关性显著,叶色越绿,稻曲病越重。另外,处理间空秕率和千粒重与病害相关性显著,但并不是由于病害造成,而是由于肥力条件造成。
This article describes the relationship between fertilization time experiments and the development of false smut in Fuhai, Guandu District, Kunming in 1992. Fertilization period planted the same day. 10 days after transplanting, 25 days after transplanting, 40 days after transplanting and blank control. The results showed that there was a significant correlation between the leaf color level and the disease in the broom pre-treatment stage, the more green the leaf color and the more severe the rice false smut. In addition, the correlation between empty grain yield and grain weight and disease was significant, but not due to disease, but due to fertility conditions.
